Abstract

Type D personality, characterized by Negative Affectivity (NA) and Social Inhibition (SI), has been associated with maladaptive health-related behaviors and unhealthy lifestyles. This study aimed to investigate the relationship between Type D personality traits with eating behavior and adiposity. This cross-sectional study analyzed data from 337 adults. The data collection tools included the Descriptive Information Form, Type D Personality Scale, Adult Eating Behavior Questionnaire, adiposity indicators. The data were analyzed using descriptive statistics, simple and multiple linear regression analyses, and the significance level was p < 0.05. The study found that the prevalence of Type D personality in adults was 22 %. Linear regression analysis revealed that NA was associated with emotional over-eating (β: 0.159, p < 0.05), while SI was linked to food fussiness (β: 0.119, p < 0.05) and satiety responsiveness (β: 0.137, p < 0.05). Regarding adiposity, NA was found to be a positive predictor for waist-to-height ratio (WHtR) (β: 0.107, p < 0.05). The study findings demonstrated that NA and SI have independent effects on eating behaviors and adiposity. It is recommended that clinicians pay attention to these personality traits, as they may influence health-related outcomes.

消极情感和社会抑制是饮食行为和肥胖的独立预测因子：D型人格特质的研究

D型人格以负向情感（NA）和社会抑制（SI）为特征，与健康相关的不良行为和不健康的生活方式有关。本研究旨在探讨D型人格特征与饮食行为和肥胖的关系。这项横断面研究分析了337名成年人的数据。数据收集工具包括描述性信息表、D型人格量表、成人饮食行为问卷、肥胖指标。数据分析采用描述性统计、简单线性回归和多元线性回归分析，显著性水平为p <； 0.05。研究发现，成年人中D型人格的患病率为22%。线性回归分析显示，NA与情绪性暴饮暴食相关（β: 0.159, p < 0.05）， SI与食物挑剔相关（β: 0.119, p < 0.05），饱腹反应相关（β: 0.137, p < 0.05）。关于肥胖，NA被发现是腰高比（WHtR）的正预测因子（β: 0.107, p < 0.05）。研究结果表明NA和SI对饮食行为和肥胖有独立的影响。建议临床医生注意这些人格特征，因为它们可能影响健康相关的结果。

期刊介绍： Personality and Individual Differences is devoted to the publication of articles (experimental, theoretical, review) which aim to integrate as far as possible the major factors of personality with empirical paradigms from experimental, physiological, animal, clinical, educational, criminological or industrial psychology or to seek an explanation for the causes and major determinants of individual differences in concepts derived from these disciplines. The editors are concerned with both genetic and environmental causes, and they are particularly interested in possible interaction effects.
